James Townsend, 33, of the 2900 block of Bero Road, died Wednesday after suffering medical complications after he and a second man were shot April 27 outside Townsend's home by two suspects wearing masks, police said.

The medical examiner ruled Townsend's death a homicide Thursday. The other male victim was treated and released from Maryland Shock Trauma Center, police said.

Police said the shooting was not connected to an ongoing dispute and charged Brian Sheppard, 20, of the 900 block of Seagull Ave. in Brooklyn, on Tuesday .

Police have not arrested a second suspect.

Sheppard is charged with attempted first degree murder, first degree assault, and related charges and the state's attorney's office is reviewing the case to determine if additional charges are necessary. Sheppard is being held without bail at the Baltimore County Detention Center.

According to online court records, Sheppard was found guilty in 2010 of witness retaliation and received a one-year sentence. He pleaded guilty in June to armed robbery and received a one-year sentence, with credit for time previously served.

Prosecutors announced new indictments Monday of Baltimore jail staff, the same day a top corrections official testified in the federal corruption trial of eight inmates and corrections officers about the difficulty containing misconduct in the system.
